Why is "learnable_prompt: false" in the config file

[5o1]

In PromptMR Plus, the required_grad of the prompt parameter is controlled by the learnable_prompt configuration parameter, which defaults to false. This seems to treat the prompt as an initial noise tensor in DIP.

I tried to train with learnable_prompt: false set unchanged(false) and the results were good (SSIM 0.975+)

Does this mean that the PromptBlock is not used to store general figure features of the dataset?

I'm confused. Can anyone clarify this for me?
